"I have used Bosch HSS bits before so I knew what I wanted when I needed some. These are great quality- very sharp and straight and went straight through steel that my other bits were struggling to get through. Highly recommended."
"its a very good set to buy. Use to have a cheap set of metal drill bits, that failed to drill on wood, only use them for a few holes, and straight a way started to brake and needing to be sharpened. Since a bought this Bosh kit of drill bits, didn't had any problems. been using them for a week now. done at least 400 holes with the 2mm, between metal and wood, still look sharp and didn't break. very good purchase."
"These bits are great, no signs of bluntening, nice sturdy case, essential for anyone's tool kit! I've had other brands before, and been dissapointed how long they lasted. These are in a different league!"
